“The region is becoming increasingly mountainous. The road is flanked by very dense virgin forest; in some places it is becoming quite rough and difficult to negotiate” – Saint-Hilaire, April 25, 1822
Vilmar da Silva, a businessman from the Brazilian city of Bananal, found it strange when he spotted from his car a fiftyish gray-haired man who looked like a foreigner.
